Cover Story: This work analyses the design of a receiver for the production of thermal energy inserted in an existing dish CSP plant at the Energy Center of the Politecnico di Torino. Considering the average solar irradiance for Turin, the surface heat flux was used to obtain a suitable internal temperature for thermal storage. An LCA analysis was conducted to compare the emissions generated during the production of the main components of the CSP plant with the emissions generated by a standard thermal energy production plant. It can be concluded that the production of the main components of the CSP plant results in lower greenhouse gas emissions than the operational phase of a conventional natural-gas-fired water heater (1.6 kg CO2/day). View this paper
